The previous reviewer has become immune to images like these. Many people can no longer conceive of sharing anything with their neighbors. This film harks back to a time when people were becoming aware of reduced neighborliness.
When I was growing up, Mayday celebrations were a pagan-influenced day of Morris dancing, songs and prayer. No communist connotations at all. To associate sharing with communism is the sign of a mind deeply affected by McCarthyist nonsense.

Another in the Encyclopaedia Brittanica series on family life, this time focusing on a rather broad definition of neighbors, aimed at first or second graders. Neighbors, in this filmstrip, is used interchangibly with community, talking about not only how neighbor sharing things, like the stereotypical borrowing of eggs, but larger community focus, such as paying taxes to support fire protection or participating in school activities. It also shows instances when neighbors *don't* share, such as not having a dog on a yard.
This filmstrip is clearly the product of a bygone era. At the start, Steve thinks that his mother can't buy eggs because "it's Sunday and all the stores are closed." White suburban community schools and neighborhood wennie roasts are presented as matter of course. All of this is presented in the context of the clearly fragmenting and nuclearized family of the postwar period, so celebrated in films like "In The Suburbs." There is something a bit odd, in that context, with the emphasis on communal harmony, especially with the inclusion of "Dad" making a Maypole. The maypole, associated with May Day, and hence Communist celebrations, is an unusual bit of subliminal symbolism when discussing and advocating the cohesiveness of the community.
Finally, why, oh, why does the filmstrip copyright notice states that "all rights for reproduction, including by Television, are reserved."? Was there ever filmstrips on TV?
